How can I regain my dignity and power?

My ex broke up with. I ended up calling him and kinda begging for a second chance. Then I reached out to him twice. First conversation went good. Second conversation I got left on delivered ( Maybe because I opened and replied to his message almost a day later)
I eventually deleted my text.

I definitely won’t contact him unless he reaches out to again.
How can I regain my power even if he decides to reach out again?
